I love punny costumes! I wanted fake sticks of butter on my fingers and saved and cleaned butter wrappers. Then I formed 3 rectangular boxes out of the butter boxes and other cardboard on hand. Cover the boxes in light yellow paper then wrap the covered boxes in the butter wrappers. Leave one end of the box open and cut some tabs around the opening. Fold the tabs into the center and the tabs will prevent your finger from slipping out of the butter box when you put them on your fingers. Wear Butterfinger colored clothes to complement your costume and let the groaning laughter start when people see your costume.
